As shown, the block 12 are preferably covered with an this device comprises a binding block 12 haV imitation leather or some similar material ing covers 14 secured thereto by hinges inas indicated at 3&1. 95 dicated generally at 15. A loose leaf bock constructed in accordance The binding block 12 is preferably made with my invention is very rigid and durable of wood and provided with a trough 16 in owing to the binding block 12 which prewhich a metal binder ring mechanism 17 is vents 'Wobbling of the bool: and the hinge 15 sa adapted to be positioned. The binding block whicin-` owing toits novel` comnia:nation `is M0 very strong and securely holds the covers to secured to the side of said binding block and the binding block.

From the foregoing description it will be apparent that I have provided a novel form of loose leaf book which is simple in construction, rigid and durable.

Having thus described my invention, I claim:

l. In a device of the class described, a binding block having a trough extending the full length of the same, a binder ring mechanism, said ring mechanism including a body having a pluralityof split iings, said body having a tongue at each end thereof, said ring mechanism being positioned in said binding block trough and a retaining block in each end of said trough and engaging said tongues.

2. In a book, a binding member, a cover adjacent said binding member, a hinge adapted to secure said cover to said binding member, said hinge comprising two strips of flexible material sewed together on a line intermediate their edges, to form four portions, one of said hinge portions being secured to the top face of said binding member, another 0f said hinge portions being secured to the side of said binding member and the other two portions being secured to said cover, one on either side thereof.

3. In a device of the class described, a binding block, a cover adjacent each side -of said binding block, hinges adapted to secure each of said covers to said binding block, each of said hinges comprising two strips of flexible material sewed together on a line intermediate their edges, to form four portions, one of said hinge portions being secured to the top face of said binding block, another of said hinge portions being secured to the side of said binding block and the other twoportions being secured to one of said covers, one on either side thereof.

4. In a device of the class described, a binding block having a trough extending the full length of the same, a binder ring mechanism, said ring mechanism including a body having a plurality of split rings and having a tongue at each end of the body, said ring mechanism being positioned in said binding block trough, a retaining block positioned in said binding block trough adjacent each end thereof and over said ring mechanism tongues, said retaining blocks being secured to said binding block, said binding block having notches therein adjacent each of said rings to allow said rings to open, a cover adjacent each side of said binding block, hinges adapted to secure each of said covers to said binding block, each of said hinges comprising two strips of flexible material sewed together on a line intermediate their edges to form four portions, one o-f said hinge portions being secured to the top face of said binding block, another of said hinge portions being the other two portions being secured to one of said covers, one on either side thereof.

In testimony whereof, I hereunto aiiix my signature.
